libtool problem

[Victor Sterpu]

I use Ubuntu server 7.10, libtool  1.5.24 and gcc 4.1.3.
I try to compile the last version of mod_auth_xradius and when I do make 
I receive the error:

if /usr/share/apr-1.0/build/libtool --mode=compile g++-4.1

libtool: compile: unable to infer tagged configuration
libtool: compile: specify a tag with `--tag'

I tryed to compile and other programs and I received the same error.
Does someoane knows how can I fix this?
